Remember that diesel fuel uses kerosene where glow engines use alcohol. The kerosene provides much better lubrication so I think it may not work exactly the same way...but close enough. I have used their process for diesels ever since I read it several years ago.
Back in the dark ages (1950's) modelers debated on whether an engine (iron/steel) needed break-in. Most CL guys said yes, most FF guys said no. The FF guys were starting their engine, peaking it out, and letting the model go. Run time a minute or so. They were essentially heat cycling the engine as described above.
I believe the cast iron is referred to as being "green" before the stresses are relieved. I've heard that in the USA, cast iron engine blocks are (or were) aged for two or three years before final milling and processing.

Sport_Pilot, you must work on some BIG model engines.
I know my break-in procedure works for me. Feel free to use your method on your engines.
